Booked in brake check as making a grinding noise. I selected 10am slot on Sunday at the Widnes branch, so I turned up at 10 when they opened along with 10 others who has the same slot booked. National called me at 2pm to say car needed £360 worth of work, but which can't be do done until the next day as they dont have parts. The following day they said the LOCKING nut had snapped and I was asked to take the car to a garage who specialises in removing locking nuts and bring it back. I picked the car up and took it to a garage I usually use who agreed to fit me in, glad I did as the work icluuding the brakes cost me two thirds less than what I was quoted my these rip off merchants. Avoid this chain as they will quote you for work that does not need doing.
